Oxidizing agent

refers to how Europium was used in old TVs as a red color, and with the colors blue and green, they would be able to display TV shows and commercials. “Fluorescing” ties into the fact that Europium glows, or fluoresces, red under a blacklight. And “oxidizing” finishes that line of the poem since Europium is known to react very quickly in air, which is why samples of the element are usually found in test tubes or a solution that won’t let it oxidize. The fourth line of the poem describes all the…

Abstract: We describe the successful synthesis of Polypyrrole-Gold nanocomposites (PPy-Au NCs) by the chemical oxidative polymerization of pyrrole with ferric chloride as an oxidizing agent, in the presence of a colloidal suspension of gold nanoparticles. Gold nanoparticles (Au NPs) were synthesized by standard citrate reduction method. Au NPs and PPy-Au NCs were characterized by Transmission Electron Microscopy (TEM), Atomic Forced Microscopy (AFM), Scanning Electron Microscopy (SEM), Fourier…

have to attach to the molecules that color (White 1989). Agents do not have to do that. The reason our hair has a natural color to it is because it is made out of pigments called melanins. Melanins…

1. Which one of the following would make the most suitable catalyst in the decomposition of hydrogen peroxide (H2O2)? A. Carbon dioxide (CO2) B. Sodium chloride (NaCl) C. Magnesium oxide (MgO) D. Manganese dioxide (MnO2) 2. If the temperature of a reaction is decreased, what effect will this have on the rate of reaction? A. It will have no effect. B. The reaction will stop. C. The rate of reaction will increase. D. The rate of reaction will decrease. 3. Given the equilibrium reaction in a closed…

Escherichia coli, a bacteria with an optimal pH of between 6.5 to 7.0 to enhance its proliferation is very commonly used in laboratories and studies worldwide due to its low cost and high effectiveness and will therefore be the bacteria of choice for this investigation. It has been shown in many studies such as the article “HdeB chaperone activity is coupled to its intrinsic dynamic properties” very recently published in the prestigious magazine Nature that bacterial growth and overall…

“The most tangible of all visible mysteries-Fire,” said by Leigh Hunt brings us to think how amazing and destructive something so beautiful can be. Fire is considered one of the four basic elements and the fact is that nothing is basic about fires. The chemical process that occurs is what we see when the fire dances in front of our eyes. In the safety field there is an increased need for fire knowledge so that we can prevention and train employees on them. There are many components to consider…

The first experiment that was performed was the oxidation of 9-fluorenol, which is the decrease of a molecule’s hydrogen content.6 The following chemicals were used in the experiment: 9-fluorenol, sodium hypochlorite (the oxidizing agent), sodium thiosulfate (the reducing agent), sodium bicarbonate, acetic acid, and acetone.3,6 To begin the experiment 9-fluorenol, acetone, acetic acid, and sodium hypochlorite were added in sulfate is added to remove excess water from the hexane layer that is…

In the last years, it has read that the electron transfers have relations with many processes, such us the photosynthesis (biology), organic synthesis (organic chemistry) or charge-transfer complexes (inorganic chemistry). It is important to know that most of the electron transfer occurs due to the metals, metals complexes and organometallic compounds. In this chapter a review of earlier electron donors and the different electron transfer will be developed. 1.1 Organic electron donors Since the…

Most people who watch crime dramas (Law & Order, NCIS, or CSI) on TV know what the cops do when they’re at a crime scene. When cops are investigating a crime scene, they spray a special type of solution involving the chemical Luminol that glows blue in the dark. The topic of this experiment is to determine what other liquids can react with Luminol to make the solution glow blue in the dark. The independent variable would be the types of chemicals used (in cups) and the dependent variable would…

Although there is no conclusive research about the effectiveness of different microbial agents, due to the features of bacteria constantly changing, there are theories about how they affect the growth of bacteria. Firstly, bleach is a disinfectant which is effective in killing bacteria due to the active ingredient sodium hypochlorite. There are theories which suggest that sodium hypochlorite has power as an oxidizing agent and when in contact with bacteria, fully oxidizes the cells of the germs…
